gomoku — game of 5 in a row
gomoku [-bcdu] [-D debugfile] [inputfile]
gomoku is a two player game where the object is to get 5 in a row horizontally, vertically
or diagonally on a 19 by 19 grid. By convention, black always moves first. With no argu‐
ments, gomoku will display a playing board and prompt for moves from the user. Valid moves
are a letter for the column and a number for the row of an empty board location. Entering
``quit" or ``resign" will end the game. You can save the current state of the game by
entering ``save" and supplying a file name when prompted. The optional file inputfile can
be used to restore a saved game.
The options are:
-b This option sets background mode. Input moves are read from standard input, the
computer picks a move, and prints it to standard output. The first input line
should be either ``black" or ``white" to specify whether gomoku has the first move
or not respectively. This option was intended for game tournaments where a referee
program handles the board display and pits one program against another.
-c Computer versus computer. gomoku will play a game against itself. This is mostly
used for testing.
-d Print debugging information. Repeating this option more than once yields more
Print the debug information to debugfile instead of to the standard output.
-u User versus user. This is mostly used for testing.
The board display routines were based on the goref program written by Peter Langston.
